Mitch Daniels did this within 3 weeks of taking over the Governorship here in IN.
he removed the requirement they join a union, and within a few short years, practically all of those affected opted out of their union and their dues.
And they workers still have a secure job with bennies.
I guess I was wrong on the dates and time....

on his first day in office, he decertified all government employee unions, removing the requirement that State employees be union members; and, within eight months, 92% of government union members quit their union.[22]
